The results of our review indicate that visual interference could determine attitudes to WTG. There was a greater likelihood of annoyance or less satisfaction if respondents could either see WTGs from their residence, or if they lgk974 thought WTGs distorted their landscape. This finding supports the conclusions of other authors who reported that visual interference from WTGs may actually be responsible for the annoyance, rather than the noise generated by the wind turbines (Jeffery et al., 2014). Based on this finding, we are less certain if the noise from WTGs themselves actually results in the annoyance, sleep disturbances or reduced quality of life observed in our systematic review and meta-analysis; this issue warrants further investigation.
It is unclear to what extent economic ties with WTGs influenced participants' responses. The inconsistency in the relationship reported across studies makes digestion difficult to ascertain whether benefitting financially from WTGs affects attitude. Therefore, we are unable to draw conclusions about this relationship based on present evidence.
